  • Extract frames from live youtube stream

    21 décembre 2022, par irman

    I want to extract frames from a youtube live event, say one frame every 5 minutes, ideally without saving the stream to my local machine. Is there a simple way to do this, possibly a combination between youtube-dl and ffmpeg that I am not figuring out ? I found a similar question for UDP streams but don't know how to include the youtube stream : FFMPEG : extract a fram from a live stream once every 5 seconds

    



    Thanks a lot in advance !

    


  • RTSP to RTMP Youtube Live only displays online for few seconds

    2 juin 2016, par Poison

    I’m trying to get the feed from an IP camera to Youtube Live. Simple enough uh.

    The command I’m using is the usual :

    ffmpeg -i rtsp://user:pass@ip:port/videoMain -f flv -r -s -an rtmp://a.rtmp.youtube.com/live2/per-sonal-code

    What happens

    Live Youtube receives the signal and says its healthy, after two or less seconds a red box appears saying they’re not receiving my signal. After that it displays "No signal". Webcam image is never shown.

    What I’ve tried

    Different parameters (-re, -rtsp_transport tcp, -s 640x480, -g 30, -r 30 ..) and different combinations of them, plus different resolutions, different buffer sizes and stream sizes, and different Ingestion settings on Youtube.

    Followed different very basic stuff tutorials.

    I’ve done it with ffmpeg in Windows 7 and Ubuntu 16.04, different networks (home and work), checked for possible port problems,...

    What confuses me

    Using streaming software like XSplit, or Manycam it actually works on the same computers !
    Also using the different command combinations, Youtube always receives the signal and its healthy before changing and displaying "No signal", its not complaining about low bitrate, or wrong format like I’ve seen in the different tutorials.

    I need to create two different streams for two cams, so ideally I’d prefer to use ffmpeg. However if anyone knows a software that can do this, please tell me. I’ve been stuck with this long enough !

    Thanks.

  • Destreamer (FFMPEG / Youtube-DL) - Can't download video, Invalid DTS, Invalid timestamps message

    1er avril 2020, par toprun91

    I'm using Destreamer a program that essentially lets you download microsoft stream videos by passing a key URL with a cookie down to Youtube-dl which then calls into ffmpeg.

    



    Whenever I try to download a video using this program I get tons of repeating lines of text (errors ?) like this :

    This continues to fill the screen and scroll with the same type of lines of text and then after a couple of hours it does eventually download the video but without sound.

    



    I am trying to work out why this is happening and why the video downloads without sound.

    



    Some key information :

    



      

    • I am using windows + powershell but also experience the same thing on
Linux (Kubuntu)

      • 


    • I am using the latest versions of FFMPEG, youtube-dl node.js

      • 


    • The program (destreamer) brings up a chromium window to authenticate.
In the Chromium window the video doesn't actually play properly and
gives Error code 0x20400003 The video plays fine in all other
browsers I have including Edge, Chrome, and Firefox

      • 


    



    Thanks for your help !
